While we do service the watches we sell in order to guarantee that they are running properly for their new owners, we do not offer watch servicing or repairs as a standalone service for our customers. With every watch that we sell and service, only genuine components are used, right down to the rubber gaskets.
As far as service costs, they can vary greatly depending on who performs the work, the type of movement, and what the watch might require as far as replacement components. Omega outlines the various base costs associated with service on their website; however, there are also many qualified independent watchmakers and service centers that will be able to properly service your watch.
